NOTE: This field has NOT been updated as part of the May 2010 Data Dictionary update. Priority for the Data Dictionary update was given to those fields that are required or strongly recommended for Artefacts Canada contribution. The Entry Rules for this field will be updated at a later date.
Entry rules
Enter a numeric date. Always record the date in YYYYMMDD order (always give all four digits of the year). Dates can be qualified by adding one of the following attributes: circa (C), prior to (P), later than (L), decade ('s), between (-) and uncertain (?). Attributes should be separated from the date with a space, except for decade ('s) and between (-). Dates can also be described as "unknown". BC dates should be expressed as negative integers. If 'circa' is used in Date of Object, From (BPD1), do not use this field.
Cataloguers rules
If only one date is known for the object, then use Date of Object, To (EPD2). If a date range is known, enter the earliest date in Date of Object, From (BPD1) and the most recent date in Date of Object, To (EPD2). If only a date range is known for the earliest date, then enter the lower value in Date of Object, From (BPD1) and the higher value in Date of Object, From (2) (BPD2). Similarly, if only a date range is known for the most recent date, then enter the less recent date in Date of Object, To (1) (EPD1) and the more recent date in Date of Object, To (EPD2). BP dates should be converted to BC dates. BC dates should be expressed as negative integers. See also, Date of Object, From (BPD1), Date of Object, To (1) (EPD1), and Date of Object, To (EPD2), and Absolute Date (ABD).
